<div dir="ltr">Hi,<div><br></div><div>I had another go compiling GROMACS 5.0 beta with bgclang latest RPM (r200401-20140129). CMake detection of OpenMP support in mpiclang failed. Detection should just work because using the -fopenmp flag is a standard way to do it. When I tried a manual compile:</div>
<div><br></div><div><div>$ ~/progs/bgclang/current/bin/bgclang -fopenmp test.c -o test</div><div>/homea/slbio/slbio013/progs/bgclang/r200401-20140129/binutils/bin/ld: cannot find -liomp5</div><div>clang: error: linker command failed with exit code 1 (use -v to see invocation)</div>
</div><div><br></div><div>That looks like a lingering Intel-ism?</div><div><br></div><div>The MPI plus non-OpenMP build seemed to go OK, but a file in our bundled lapack subset provoked a bug (attached in tarball). That file was not a problem in ~August 2013.</div>
<div><br></div><div>Thanks again for the effort!</div><div><br></div><div>Cheers,</div><div><br></div><div>Mark</div></div>
